ERTdesign is a geophysical app that estimates the depth of investigation for Electrical Resistivity quadrupoles with in-line electrodes (VES or 2D ERT measurements). The tool also calculates the geometric factor of the quadrupole and provides an estimate of the expected Vmn signal at the receiver.
The following electrode arrays are parsed:
– Wenner;
– Wenner-Schlumberger;
– Dipole-dipole;
– Pole-dipole;
– Pole-Pole;
– Gradient Array;
– Generic quadrupole: just define the coordinates of the four A, B, M and N electrodes.
This last feature is useful when estimating the real depth of investigation for arrays making use of remote poles not really at “infinite” distance from the set.

The depth of investigation estimate is performed, first, integrating the analytic sensitivity function – for the given quadrupole – and then by calculating the “median z depth”, so that the area under the sensitivity curve is equal to the 50% of the total area (Edwards, 1977; Baker, 1991).

Processing steps:
1. Select array type (Wenner, dipole-dipole,…) and display the geometry for the A, B, M and N electrodes.
2. Set the quadrupole configuration: lenght of the receiving /transmitting dipole and TX-RX distance (levels), or, for a generic array, set the coordinates of the A, B, M and N electrodes.
3. Set the field parameters for estimating the expected Vmn signal: average background resistivity (ohm m) and injected current (mA).
4. Calculate depth of investigation, geometrical factor and Vmn signal.

SmartPhoneTracker Free – Locate your lost phone

SmartPhoneTracker Free

Locate your lost phone

SmartPhoneTracker Free screenshot 0SmartPhoneTracker Free screenshot 1

SmartPhoneTracker allows you to locate your phone via GPS coordinates, useful if your phone gets lost or stolen, and for locating missing family members. Basically, SmartPhone Tracker is configured to listen for a certain text message. When it receives that text message, the program. will wake up, activate the phone’s GPS and obtain a lock. Once it has GPS satellites locked, it will send a text message with a link to Google Maps with the phone’s location and exact GPS coordinates.
If there is no GPS reception for 2 minute, SmartPhoneTracker will send the approximate Network location.

Permission info:
ACCESS_FINE_LOCATION – GPS location.
READ_PHONE_STATE – Read SIM’s IMSI for SIM replace detection.
INTERNET – Network location.
WAKE_LOCK – stay awake while searching for location (two min max).
SEND_SMS – SMS Notification.
RECEIVE_SMS – Coded SMS interception.
RECEIVE_BOOT_COMPLETED – SIM Replace detection on boot.

Muy útil si estas en una ciudad desconocida y te encuentras en una calle,necesitas llamar un taxi,le das a la aplicación y te dice rápidamente en que calle estas, dándole a mapa te muestra tu posición en Google Maps.
El programa esta creado con App Inventor y hace una precarga de la posición usando el GPS así que tarda en darte el nombre de la calle bastante menos que entrando en Google Maps que tiene que cargar el mapa.La puedes usar mientras te llaman y comunicar donde estas sin necesidad de buscar un sitio de referencia o buscar el cartel de la calle.
Espero que os sea útil.

Contact Remover screenshot 0Contact Remover screenshot 1

Small tool to let you delete multiple contacts. Select one, many, or all. Search to identify contacts to delete.

Touch to show contact details in app to help you decide which contacts to delete. Search works across all contact information (name, company, address, etc.).

*** For more features such as select by account, copy, move, and merge, see Contact Remover Plus!

NOTE: May not show or delete Facebook contacts depending on phone.

*** Please email me if you have any problems, questions or suggestions. We developers CANNOT RESPOND to comments left as feedback in the market-google just doesn’t give us any way to do it, so please email us!

I suppose I should point out that for those reviewers complaining that this app does nothing that the built-in contact app doesn’t do, please remember that not all phones have the same built-in apps, and that the contact app is often customized by the phone manufacturers or carriers to add features. Lots of phone don’t have a bulk-delete capability, which is why I originally wrote this.

සන්හිඳ (Sanhinda) helps you to type in Sinhala with your Android Device.

As you know, Android devices doesn’t have a Sinhala keyboard for you to type your Facebook wall post or Twitter update in Sinhala. Here Sanhinda helps you to do all these in simple two steps. All you have to do is type in your text with English keyboard, meantime Sanhinda transliterates this text in to Sinhala for you Offline. After you type your post, status, email in Sinhala you could share it with your friends within app it self.

Application Features include,

* Transliterate text into Sinhala
* Share on Facebook
* Post to Twitter
* Send via Email, Bluetooth etc…
* Message a friend if device supports

NOTE: Kindly consider that some combinations of sinhala phrases will not render properly on Android Devices. But it will be shown correctly on web browsers, etc after you complete your post.
